Add Corner Radius for Table and Matrix Visuals

Problem:

Currently, Table and Matrix visuals do not have a built-in "Corner Radius" option in the General format settings. To create rounded corners, we have to use a Shape as a workaround behind the table.

Why this is needed:

1. The shape workaround makes the PBIX file heavier and harder to maintain.

2. We cannot have Cards and Buttons with rounded corners, but not Tables. It looks inconsistent.

3. Modern dashboard design needs this feature for a professional look like in Figma and Canva.

Request:

Please add a "Corner Radius" slider under General > Properties for Table and Matrix visuals, just like we have for Buttons, Cards, and Slicers.

This will help all Power BI developers create clean and modern dashboards easily.
